Circuits and Systems Enabling Silicon-Photonics Signaling

Computing and data communications have changed the way we work, communicate, socialize, learn and educate. To maintain and improve our lifestyle, and to solve most of the challenging problems we face as a society, e.g. developing personalized medicine or a sustainable management of energy resources, our need for super-computers and data-centers that can process massive amounts of data with manageable power continues to grow. This need has driven the exponential scaling of CMOS technology and the rise of multi-core and inter-linked data processing and communication in the last decade. However, this aggressive scaling is now being imperiled by the slower pace of scaling of Input/Output (I/O) data links. For example, ultra-high performance computing systems over the next decade are expected to require Terabytes per second of aggregate data throughput over I/O links. Based on the existing trend, this means providing 10 times the I/O bandwidth for 1/10th the power over the next decade, and presents a real challenge that cannot be addressed by standard copper interconnects.
